Don't be fooled by the high payouts though, because generally there's a reason why they're higher, and it's usually because they are more difficult to convert. If not that, then you still have to watch out due to higher cometition and therefore generally a much larger budget is required to test highly paying/highly competitive offers.
Thats not to say they are all like that, but it is generally best to choose offers based on what you think you could promote/convert the best.
For example, you could make great money promoting an offer with a $1.00 payout if you're converting at 10% and paying $0.05 for your clicks = for ever $0.50 you spend you earn $1.00, thats 100% ROI. Now all you would need to do is scale up in terms of the ammount of cheap/converting clicks you get.
Conclusion: Look at more than just the payout
